There are a lot of reasons the Miami Heat lost to the Boston Celtics Tuesday night in Game 5 of the Eastern Conference Finals, putting the team down 3-2 heading back to Boston for a potential series clincher. Dwyane Wade got going too late, our role players can’t live up to their roles, Chris Bosh’s torn tummy, Paul Pierce’s unlikely tre in Lebron James’ face, Eric Spoelstra’s questionable coaching, the Heat weren’t getting back on defense late in the game (even after scoring!), and my leading candidate: the Heat’s lack of identity, a debilitating weakness when the going gets playoff tough and a problem that the Celtics clearly don’t have.
